do it yourself. if you have any questions pm me ive installed dozens, and should be able to dig up some instructions with pictures
look under your dash above the hood release. there should be some hiddin wires taped up (red black blue brown (not used) and LT blue. if there isnt any, your truck will require a wiring harness that simply plugs in the same area above and left of your brake pedal. you'll see it when you look. i beleave your truck should already have the harness wired in though.
when you buy a brake controller it will have the wiring diagram in the instructions. its all prettymuch color coded but it is a negative ground meaning your red from the truck will connect to the black on the controller
after you have this hooked up, if it doesnt work (every modle is different) pull the panel off of the fuse box under the hood. on each side (front and back) there will be 1 red wire with an eye taped up to the loom tubing on the wires outside the fuse box. (they try and hide them) you'll have to find a bolt to fit the studs on each side of the fuse box, and it may require plugging a jfuse into the fusepanel (it will be labeled if it needs it)
if your controller works after you simply hook it up you wont have to mess with any wires on the fuse box or installing a fuse
simple as that :mrgreen:
